Kellen Moore most likely to be Saints coach; Saints meeting with Moore again after the SB, Kellen Moore has begun working on assembling coaching staff

Even if that rumour is true, there are no Quarterbacks to go after in this draft. So, no, it shouldn't change the draft strategy at all.
Sure, there aren't any that people are calling a sure thing, but that doesn't mean there are none. Now getting one at the spots you're picking becomes more difficult when there are so few. And it's never really a sure thing so there are risks to selecting one. Especially if you had to move up to get one. So I agree with your conclusion that it should change the draft strategy. But if Ward were to somehow fall to 9 (he won't) or Dart was there at 40 you would have to consider drafting one of them.
